I've changed it so this used a fixed entry while the other uses a changed entry, so this makes it clear that this is a bug fix, and the other is a part of the image upgrade.

[Emilgardis]

they went from 4* to 5* in this bump, no?

so shouldn't this be

change powerpc64, riscv64, and sparc64 *-linux-gnu images to use a 6.x kernel instead of a 4.x kernel.

[Emilgardis]

also, the changelog file should probably be renamed to 591-1095.json

[Alexhuszagh]

Done, I've consolidated the two and changed the changelog to be something like:

[
    {
        "type": "changed",
        "description": "upgraded most linux images to use a 5.x kernel instead of a 4.x kernel.",
        "breaking": true
    }
    {
        "type": "changed",
        "description": "updated powerpc64, riscv64, and sparc64 *-linux-gnu images to use a 6.x kernel instead of a 4.x kernel.",
        "breaking": true,
        "issues": [1094]
    }
]

bors r+

If you really need kernel version 5 for these targets, consider using an older version of the image found on for example https://github.com/cross-rs/cross/pkgs/container/s390x-unknown-linux-gnu/versions
